Flood Risk Guayaquil: A critical analysis on inundations

Despite several researches about the hydrological and hydrodynamic system of the Guayas region, elementary insight of the total system was lacking. Therefore, the purpose of this study was to create a general overview regarding floods. Besides, basic solutions are proposed for preparing Guayaquil against floods which might be present in the...

Printing a stainless steel bridge: An exploration of structural properties of stainless steel additive manufactures for civil engineering purposes

The potential of additive manufacturing is great: highly complex and efficient structures can be manufactured with hardly any waste material. While high-tech industries such as aviation and medicine have already embraced additive manufacturing, civil engineering is lagging behind. Research on the structural properties of additive manufactures in...

Dwarskracht in zinktunnels

With the introduction of the Eurocode, different formulas are used for shear tests in concrete structures than the previous Dutch standard.These formulas are often used in new building designs. If the result compared with the Dutch standard is either favorable or unfavorable, the design should be modified. It is interesting to research the...

Preliminary study of river- and beach processes in the Matina region of Costa Rica

The starting point for this project are the severe erosion problems at the Pacuare Nature Reserve, situated on the Caribbean coast of Costa Rica. The Reserve’s installations are situated next to a lagoon which is separated from the open sea by a barrier beach. The lagoon is connected on the landward side to local river? and channel system....

On the precision and reliability of GPS networks computed using the double difference observable

Bij het meten van een netwerk met behulp van GPS Is de meest gebruikte waarneming de dubbele verschilmetlng (double difference). Tijdens het doen van deze waarnemingen kan men gebruik maken van verschillende satellieten CSV's, space vehicles). Uiteraard is het te verwachten dat de geometrische verdeling van deze satellieten van invloed is op de...
